Currently running the Axe with cab sims on, into an SLA-1, then into a pair of ADA cabs with one Eminence Delta Pro 12 in each. The sound is good, but just not quite "there" yet for me. I'm thinking about switching to a QSC K12 to increase the portability of my whole rig, and to see what all the hype is about the QSC K series. Can I expect a noticeable difference in sound quality when switching from my current setup?
